2012 Cayenne S DTC's ???
Getting DTC DME U0414 and All Wheel Drive 000125 & 000110 DTC's. Can't find much info. on any of the codes. Any help is appreciated.
The car is at my local Indie shop. We just replaced the battery with a new one and the valve lift control solenoid based on previous DTC's. The DTC's in this post are new ones FYI.

I am going to take my iCarsoft POR II over there today to see what I can find.

I would hope the POR would have the descriptions of what the trouble codes mean and what modules they are coming from. OBD-II error codes are "P" codes, P001-P999 are "generic codes" - meaning they are standardized and all manufacturers are supposed to use them to report on the same thing. P1001-P1999 are manufacturer specific codes - so what these are reporting can be manufacturer or even model specific. The codes you're reporting are the wrong format - and the one starts with U rather than P.. so.. dunno. A Porsche specific tool should be able to tell you what the code is indicating. iCarScan, Durametric and PIWIS do. It sounds as if POR doesn't. I would not expect a 4-wheel-drive error code to be reported by a generic tool since that error code lives in the 4WD control module, not in the engine ECU.

Sorry for the confusion. The codes were the same with the iCarScan POR II with the latest software. They also were available as Porsche specific codes direct from Porsche. More info. to follow after flushing x-fer case.

Great. I wasn't too confused - I'm just puzzled that all the iCarSoft-POR-II (which is different from the iCarScan X431) gave is the code without any explanation of what it means. iCarScan generally gives a fairly compete explanation of the error codes it reads, and what module they were found in. Awaiting results after flushing the transfer case takes place.

Sorry, my bad here is the Paul Harvey version of the DTC's:
1. DME (01)
1.1 U0414...check transmission control unit fault memory content
2. All wheel drive (02)
2.1 000125 PSM activation by all wheel drive control
2.2 000110 Torque trasnsmission faulty
My local shop is recommending replacement of the x-fer case stepper motor??? Any thoughts???
Thanks in advance.

As far as the stepper motor - do they have anything other than the error messages to base this on? The 955/957 hi-low range stepper motors were known to fail - at least failure wasn't uncommon (mostly if they were never used..) I haven't seen any pattern like that on the 958 stepper motors - I believe I recall one report of a stepper motor failure. It gets expensive to trouble-shoot by replacing parts..
I noted that you recently replaced the battery. Oddball failure/codes can often be tracked back to a bad battery, and once they're cleared they never come up again. I'd be especially suspicious of the memory error "1.1 U0414...check transmission control unit fault memory content" - since the memory may have been being written to at the point the battery failed or was disconnected.
Usually the codes also include the information on how many times they occurred and if they are "still present now".. (meaning the system is currently reading the same code.) If these were 1 time error codes and there wasn't the message "still present now" - if it was me (and you're not.. so take that into account, I sometimes do dumb things), I would erase the codes and drive it to see if they reappear. If they don't - they're probably phantom codes - one time error code cause by a low voltage condition.
What are the symptoms you're experiencing when driving it?

OK here is an update. Finally got a 2nd opinion at the Porsche dealer. Front & rear diff's all check out. Transmission checks out. Fault is with the transfer case. Replacement quoted ......I had to sit down @ $5664.97. They have no tools or authorization to replace the stepper motor. What I was told is that at around 1000 NM the case faults out???? More discussion on this when I visit the dealer in the next couple of days. I can have the stepper motor replaced at the local Indie shop for around $1000 which was their initial recommendation prior to the dealer visit. No guarantees that this will fix the problem (could be the clutches) but is directionally correct. If the stepper motor replacement alone does not fix the issue then that is sunk cost. X-fer case fluid is clean no issues thanks to this and other forums on this topic.
FYI my PiG has the -108 X-fer case that must of been replaced prior to my ownership.
I have more research to do on the stepper motor functionality but wanted to solicit opinions in parallel. Thanks in advance for any advice on a cost effective path forward.

As an update. Tried a replacement x-fer case servo/stepper motor still same errors. Must be the case itself as the Porsche dealer diagnosed. Since there are other issues (bent x-fer case cross member) that the PO did not disclose and was subtle enough to be missed on a PPI, I am going to have the dealer fix all of the issues. At least I bought the vehicle "right" now I am going to be back almost even $$$ if I would of bought from the dealer. Oh well. Thx for all of the advice on the various X-fer case threads.

Update: new transfer case installed and under body work completed plus updated new cross member. Eight grand for frame & under body work, new transfer case, battery replacement, and interior & exterior detailing. Brutal $$$ but now have 24K warranty on x-fer case. PiG drives better than I ever remember. Suspension "dropped" while at dealer. They said this is becoming fairly common in very cold weather. $150 for new 30 amp fuse and relay/timer. They keep these parts in stock. Next time only going CPO route.
After driving with the new X-fer case wow what a difference. I was going to change the transmission fluid at 80K proactively but the dealer talked me out of it. Base on my experience most of the shifting/hunting issues both on acceleration and deceleration were due to the X-fer case. Like driving a new vehicle. I guess it should after all of the $$$$ spent.

Hey quickster2, just wanted to say a big thank you for your post! I too am going thru this now. Just like you, I had your codes plus others (couple HangOn actuator fuses were blown) and my indie also said it was the stepper motor. It goes into the Porsche dealer tomorrow, so glad I waited before having them replace the stepper motor. You just saved my some $$$. Thanks again. This goes to show that whatever donation you provide to this forum is totally worth it!
p.s. - ditto on the cold weather air-suspension issue.

You beat me to this. Was going to suggest same thing. I'm surprised dealer didn't mention this. Although i think he has physical damage down there which might void all warranty completely.
